[GRASS5] i.target: parser support added

[Markus Neteler]

Hi Bob,
hi all,

thanks for your contribution: i.target with parser support.

I have fixed a few traps (checks which cmd line parameters
are allowed) and uploaded to CVS.
the original INTER version lives in i.target/inter now and
is in use for the inter mode (due to GRASS front.end).

i.target help
 
Description:
 This program targets an imagery group to a GRASS location and mapset
 
Usage:
 i.target [-c] group=name [location=name] [mapset=name]
 
Flags:
  -c   Set current location and mapset as target for of imagery group
 
Parameters:
     group   Name of imagery group
  location   Name of imagery target location
    mapset   Name of target mapset

The HTML page is also updated.

Next to come: i.rectify... (and i.group)

Then geo-rectification can be done scripted.

Best regards

 Markus
